Distribute or not? suppose you need to compute z = (a + b)(x + y), where a and b are m × n matrices and x and y are n-vectors. (a) what is the approximate flop count if you evaluate z as expressed, i. e., by adding a and b, adding x and y, and then carrying out the matrix-vector multiplication? (b) what is the approximate flop count if you evaluate z as z = ax + ay + bx + by, i. e., with four matrix-vector multiplies and three vector additions? (c) which method requires fewer flops? your answer can depend on m and n. remark. when comparing two computation methods, we usually do not consider a factor of 2 or 3 in flop counts to be significant, but in this exercise you can.

Resources and capabilities, such as interpersonal relations among managers and a firm's culture, that may be costly to imitate because they are beyond the ability of firms to systematically manage and influence are referred to asanswers: socially complex.causally ambiguous.path dependent.the result of unique historical conditions.

Suppose that kenji, an economist from an am talk radio program, and lucia, an economist from a school of industrial relations, are arguing over health insurance. the following dialogue shows an excerpt from their debate: lucia: a popular topic for debate among politicians as well as economists is the idea of providing government assistance for health benefits. kenji: i think it is oppressive for the government to tax people who take care of themselves in order to pay for health insurance for those who are obese. lucia: i disagree. i think government funding of health insurance is useful to ensure basic fairness. the disagreement between these economists is most likely due to . despite their differences, with which proposition are two economists chosen at random most likely to agree? lawyers make up an excessive percentage of elected officials. minimum wage laws do more to harm low-skilled workers than them. tariffs and import quotas generally reduce economic welfare.
